Add ability to filter pipeline Runs view by repository

[bengotow]

In the case below, the top run was actually for a pipeline of this name in another repository:

To fix this, we need to allow the pipelineRuns query to be filtered by a PipelineSelector, not just a pipeline name. (And Pipeline Run Storage needs to keep the repo location name and repo name to make this filter possible):

@gibsondan Is it possible to add a repository selector to this filter?

[gibsondan]

we can absolutely add repository name and repository location name to this - one thing that we will lose if we do that is pipelines created via direct execution of the PipelineDefinition itself separate from any repository - e.g. "dagster pipeline execute" or calling execute_pipeline programatically. Not sure if that's actually a problem or not.
